Characterization of NiCuZn Ferrite Slurry and Green Sheet Using a Water Mixed Medium System

The characterization of NiCuZn Ferrite (NCZF) slurry and green sheet using a water mixed medium system has been studied. The raw materials and the NCZF powder were ground by wet ball milling with the 0.7wt% polyacrylic ammonium salt. The 21vol% of NCZF slurry was prepared by a ball milling. The polyacrylic vinyl copolymer (Mw; 60000) was used as a binder. The mixture of distilled water, Isopropyl alcohol (IPA) and 2-butoxyethanol was used as a dispersion medium. The water content of medium varied from about 40% to 80%. The NCZF slurry was characterized with the water content. The microstructure and the mechanical property of the NCZF sheet have been investigated.
